Flavonol glycosides acylated with 3-hydroxy-3-methylglutaric acid as systematic characters in Rosa

The previously unrecorded 3-O-α-l-rhamnopyranosyl-(1→2)-[6-O-(3-hydroxy-3-methylglutaryl)-β-d-galactopyranosides] of quercetin (4) and kaempferol (10) showed a discrete distribution among 71 species of Rosa that informs phylogenetic analysis of the genus.
